Installed a pair of Bilstein's on the front (incredible difference from the old junk that had been there) but couldn't get to the rears because I can't get a socket on the damn upper bolts. The body of the shock is in the way and keeps the socket from going on. And the bolts are recessed, so I can't get a wrench on there either. Not even sure how they were installed. I can't wait to get them changed though, because the Bilsteins in the front made such a major difference in how the truck rides.
Oh, and I found and fixed the short that was blowing the fuse for my parking lamps/markers/dash lights. Actually, it was an incredibly lucky find... I thought it was in the rats nest of wires under the dash, so I put it off and went to do the shocks first. Taking the 3 ton jack out of the sidebox though I noticed that it had been moving around and had crushed the butt splice for the marker light outside the box. It was just enough to short the wire, through the jack and its steel wheels, to the box itself when I hit the brakes or a good bump. Fixed the splice, heat shrinked the wire and added a wooden block to keep the jack from crushing it again.

I just looked 'em up and it seems the old shocks weren't "junk"... They were Monroe Reflex shocks, which are supposed to be pretty good monotube units, but the difference between the ride from them, and the ride from the Bilsteins is like night and day.
